Description

  The present invention relates to an information search system, an information search terminal, an information search method, a program, and a recording medium. Specifically, the present invention relates to a simplified keyword input and high accuracy for a specified keyword search request. Related to providing search results and related advertisements.

  In recent years, with the spread of the Internet, various information can be extracted from computers all over the world connected to a network. In this case, by setting a computer containing the information to be provided in the Web server, it can be easily provided via the Internet to information terminal devices possessed by people all over the world who want the information. You can get the information you think quickly.

  For that purpose, the information provided by Web servers all over the world is collected in advance and the table of contents information is stored. When a keyword (word) representing information that people want is input, Search engines are provided that search all the information contained in the table of contents information and display the results as a list.

In general, in order to obtain desired information, it is ideal to specify a single keyword and obtain an appropriate search result.
However, the same word is used in different meanings depending on the field and situation, and is particularly noticeable in the case of proper nouns and abbreviations (abbreviations).
For example, the term “Smart Taggs” is the name of Microsoft's user interface technology in the field of information processing software, and is also the name of RF-ID technology in the same information processing media field. “ATM” is an abbreviation of “At the Money” in bank ATMs (automated teller machines) and finance, and an abbreviation of “Asynchronous Transfer Mode” in the communication field.

  In this way, in a general search engine, one keyword is insufficient, and an appropriate search result cannot be obtained unless an AND search is performed with about three keywords to eliminate unnecessary information. It has been broken.

  On the other hand, the banner advertisement displayed when the target web page is accessed is convenient for finding something interesting or looking for by chance, but it is relatively rare to find an appropriate banner advertisement. In recent years, the advertising effectiveness of banner advertisements has declined. For this reason, the advertiser of the banner advertisement is trying to display something that attracts the customer's attention, but it is not always possible to accurately grasp the customer's psychology and preferences. In addition, there is no real-time performance and lacks impact on customers.

Recently, an advertisement type search service has come to be used in order to overcome this situation. This ad-based search service allows keywords to be priced per click to advertisers, displays ads in the order in which they pay the highest unit price, and the advertiser is charged for the number of clicks multiplied by the unit price, A part of the billing amount is paid to affiliated sites that display advertisements. This is an advertisement called PPC (Pay Per Click) or PFP (Pay For Performance). Has been introduced to secure profits.
In the same way as general search results, advertisements of companies that bid on keywords are displayed in the form of text links at the top of the search engine search results.

  This ad-type search service links only in response to specific keywords specified by the user who performed the search, so compared to the conventional banner ads that linked regardless of the user's intention, The clickthrough rate is quite high.

However, a keyword input by a user is not necessarily a keyword that is highly interested for the user. For example, when a user is reading a document of interest, the search service may be used because the translated word in the document is unknown.
As a technique for providing such information of interest to the user, there is a technique disclosed in Patent Document 1.

The technology of Patent Document 1 automatically adds words that reflect user preferences from information such as document files that are not directly related to information search stored in a terminal device that is usually used by the user for information search. Extracted, classified for each relationship type of words, and stored in the preference information storage means.
In addition, when the user performs an information search, the input search keyword and an auxiliary keyword related to the search keyword are extracted from the preference information storage unit. The search result of the search keyword is used to estimate the user's daily behavior pattern using the motion related auxiliary keyword, and to classify and display the result according to the estimated behavior pattern.
Thereby, even if the user is unfamiliar with the keyword setting, the user's preference can be reflected and an efficient information search can be performed.

  However, in Patent Document 1, when a designated search keyword is not necessarily a keyword of high interest to the user, it cannot be said that the search result reflects the preference. Further, in Patent Document 1, in the case of an advertisement search type service, it is not always possible to provide advertisement content that reflects the intention of the advertiser and is highly interested by the user.

  In addition, in the advertisement type search service, in order to reflect the user's interests and preferences, the URL of the Web page viewed by the user may be acquired. In this case, all of the Web pages are acquired by the acquired URL. There is a high possibility that information will be seen and damage to privacy will be caused.

  On the other hand, browsers that display and operate web pages are generally operated only with a mouse. Therefore, when a keyword is input by keyboard input as in a conventional search engine, the user interface is inferior and the operation method However, there is a problem that workability is poor.

In order to solve the above problem, in Patent Document 2, a word in a document displayed on the screen is designated by a mouse operation or the like, and the designated word is searched for as a keyword. A comfortable operating environment is provided by displaying it on the screen.
As a method for selecting a word in a document displayed on the screen or a part of the document by a mouse operation, there is the following method (see Patent Document 2).

(1) A word including the cursor position is selected by single-clicking the left mouse button.
(2) The specified range is extracted as a word or phrase by dragging while pressing the left mouse button.

There are also various forms of the display and display location of the processing menu applied to the range selected as described above.
First, for menu display operations,
(1) A method in which a processing menu is displayed by operating the right mouse button after selecting a word or a part of a document. In this case, the processing menu includes other functions not related to the system (copy or cut) Or the like) is displayed in a mixed manner, and it becomes difficult to find out which function of the system is associated with an increase in processing functions.
(2) A special icon or the like is displayed in the vicinity of the selected word or part of the document, and the right mouse button is operated on this (the selection is reset if operated in another place), and the processing menu is displayed. In this processing menu, only the processing functions provided by the system (for example, various services such as web search, dictionary search, translation, etc.) can be displayed, so that the processing functions of the system increase. Even an excellent operating environment can be provided.

For the location of the menu,
(1) By displaying as a pop-up menu in the vicinity of the selected word or document, the correspondence with the selected word or part of the document can be clarified, but the surrounding document contents are hidden. There is a problem.
(2) By displaying at predetermined positions on the display screen, for example, at the four corners of the display screen, it is possible to avoid hiding the selected word and the surrounding content of the document.

To select a word or a part of the document in the displayed document, move the cursor and the word to be selected, etc., and click or select the third button of the mouse. Select the range of the part by dragging the third button of the mouse. This method is the same as the button operation using the left button described above.

  When this third button is used for selection, the highlighted part or highlight is displayed so that the selected part can be seen, and the web search, dictionary search, translation, and information search (AND, OR) provided by the present invention are immediately provided. A menu listing only the various services such as is displayed. The user selects a desired menu from the menu with the third button (either the left button or the right button).

  Therefore, the methods (1) and (2) are excellent in coexistence with a small difference from the operation method of the conventional personal computer. However, in (1), there are two stages of word selection and menu display, whereas in (2), word selection and menu display can be performed simultaneously.

The keyword extraction unit 11 passes the keyword extracted from the browsing document delivered from the user I / F unit 10 to the search request unit 12 as an auxiliary keyword.
FIG. 2 is a block diagram illustrating a functional configuration of the keyword extracting unit 11. In the figure, the keyword extraction means 11 includes a morpheme analysis means 111, a word evaluation means 112, and a basic keyword database (hereinafter, the database is abbreviated as DB) 113.
First, the keyword extraction unit 11 sets a range for extracting a keyword to one of the following. Further, which of these is used as the extraction range is determined in advance.

(1) When an input keyword is selected and specified by a word in the browsed document, a sentence in the vicinity of this word is targeted.
(2) Target sentences in the browsed document within the range displayed in the window.
(3) Target the entire browsing document.

A sentence in any of the above-described ranges in the browsed document is divided into word strings with parts of speech by a morphological analysis unit 111 which is a known technique.
The basic keyword DB 113 holds the part of speech and the importance for each word. The importance is set to a large value when a word such as a noun is used as a keyword, and is set to a small (for example, zero) value when the word is a part of speech other than a noun or a word that is not useful as a keyword.

The word evaluation unit 112 refers to the basic keyword DB 113, extracts the importance for each word in the word string divided by the morpheme analysis unit 111, and arranges the importance in descending order. A predetermined number (for example, about 3 words) of the sorted importance items are extracted and used as keywords.
The keyword extraction unit 11 outputs the extracted keyword as an auxiliary keyword. Further, an evaluation score calculated from the importance can be added to the auxiliary keyword as attribute information. This evaluation point may simply represent the order of importance, or may be a weight corresponding to the importance.

  The search request unit 12 passes a search request composed of the input keyword passed from the user I / F unit 10 and the auxiliary keyword passed from the keyword extraction unit 11 to the search unit 20.

The search means 20 searches the information storage means 21 by AND search in which the input keyword and auxiliary keyword passed from the search request means 12 are ADN-linked, and passes the search result to the result notification means 22.
Here, the information storage means 21 is at least one document database or file storing a plurality of document files composed of Web documents previously described in HTML, XML, or the like or documents described by an application such as a word processor.

In this AND search, a search that emphasizes the input keyword is usually performed over the auxiliary keyword. However, in the case of an auxiliary keyword to which an evaluation score is added as attribute information, a search that reflects the evaluation score in weighting is performed. (The processing of the search means 20 is performed by a search service called a normal search engine.)
Further, an OR search in which an input keyword and an auxiliary keyword are OR-coupled may be used for the search.

  The result notification means 22 adds attribute information such as a title, an abstract, a location where this document exists, and a URL indicating the location where the related document exists, to each document of the search result passed from the search means 20. A Web page that can be displayed by any one of the display methods is created and passed to the user I / F means 10. The display order may be a ranking order as information that the user desires based on search conditions such as input keywords and auxiliary keywords.

(1) First display method:
A Web page that directly displays search result documents and information on each tab is created so that a plurality of pages can be switched and displayed like a tab browser.
(2) Second display method:
A Web page that displays a URL list of search results is created so that it can be displayed in a normal browser display or a dedicated result display dialog.

Next, the processing procedure of the first embodiment will be described using the flowchart of FIG.
The user inputs a part or word of the document being browsed as an input keyword with a mouse operation (step S10), and selects a search service (step S11).

  A keyword is extracted from the browsed document, and this keyword is used as an auxiliary keyword (step S12). For keyword extraction, first, the range of keywords to be extracted is the range near the selected input keyword in the browsed document, the range displayed in the window, or the entire browsed document. Split into columns. Next, with reference to the basic keyword DB 113, the importance of each word in the divided word string is extracted, and the importance is arranged in descending order. A predetermined number (for example, about 3 words) of the sorted importance items are extracted and used as auxiliary keywords.

A plurality of document files made up of Web documents or documents created by an application are searched by AND search of the input keyword and auxiliary keyword (step S13).
In this AND search, a search that emphasizes the input keyword is usually performed over the auxiliary keyword. However, in the case of an auxiliary keyword to which an evaluation score is added as attribute information, a search that reflects the evaluation score in weighting is performed.

  For each document in the search results, create a Web page to which attribute information such as URL indicating the title, abstract, the location where this document exists, and the location where the related document exists is added, and display it on the display device, output device, etc. / Output (step S14). This display order may be a ranking order as information that the user desires from search conditions such as input keywords and auxiliary keywords.

  With the above configuration, the content of the document being viewed is used in addition to the keyword input by the user while maintaining a comfortable operating environment with a conventional mouse, so that even one input keyword can be used by the user. The intended search result can be obtained.

<Embodiment 2>
The problem in the first embodiment described above is that since the auxiliary keyword is obtained only for the current browsing document, there is a small amount of information and the user's interest may not be accurately extracted.
In the second embodiment, the context information includes not only the document being browsed but also the input keyword and the information of the browsed document in the process of obtaining the document being browsed.

  FIG. 4 is a block diagram showing a functional configuration of the second embodiment in which auxiliary keywords are improved using the keywords extracted by the keyword extracting means 11. In the figure, the functional configuration of the second embodiment includes a user I / F unit 10, a keyword extraction unit 11, a user keyword management unit 13, a user keyword DB 14, a search request unit 12, a search unit 20, an information storage unit 21, and a result notification. Means 22. Here, the same functions as those in the first embodiment are denoted by the same reference numerals, and only differences will be described below.

  The user keyword DB 14 is a data file that holds a keyword usage history extracted from a document browsed by the user, and maintains and manages the keyword and the total number of evaluation points or the total number of occurrences of the keyword for each keyword.

  The user keyword management means 13 takes out the evaluation points (or the number of appearances) corresponding to the keywords registered in the user keyword DB 14, arranges the evaluation points of the keywords in descending order, and sets the keywords with large evaluation points to a predetermined number (for example, (About 3) are taken out as auxiliary keywords.

  Next, the user keyword management unit 13 refers to the user keyword DB 14 and newly registers the keyword when the keyword passed from the keyword extraction unit 11 does not exist. When newly registering, if an evaluation score is added to the keyword, this evaluation score is set as an initial value. If no evaluation score is added, “1” is set as the number of appearances.

  Moreover, when the keyword passed from the keyword extraction means 11 exists in the user keyword DB 14, the user keyword management means 13 adds an evaluation score to the same keyword if an evaluation score is added to the keyword, The user keyword DB 14 is updated. When an evaluation point is not added to the keyword, the number of appearances is incremented by 1, and the user keyword DB 14 is updated.

  Here, after the auxiliary keyword is passed to the search request means 12, the user keyword DB 14 is updated because the keyword extracted from the current browsing document has no influence on the evaluation score and the number of appearances. The auxiliary keyword is determined based on the history information.

  Further, even if the keyword is frequently used in the past, the user keyword DB 14 is maintained about once a month so that it is not selected as an auxiliary keyword when it is not frequently used recently. In this case, the last update date and time of the evaluation score is held in each keyword of the user keyword DB 14, and maintenance is performed so that the interval between the last update date and the current date and time increases and the evaluation score decreases.

  Furthermore, not only the keyword extracted from the browsed document but also the evaluation score may be added to similar words of the keyword. The evaluation points for similar words at this time may be accumulated, for example, by weighting the evaluation points of the keywords.

  The keyword accumulated in the user keyword DB 14 may be registered not only as a keyword extracted from the browsing document but also as an input keyword. However, since keywords extracted from browsing documents often include input keywords, there are few merits of registering input keywords. However, weighting the accumulation of evaluation points with keywords extracted from input keywords and browsing documents. This scheme is useful when doing so.

Next, the processing procedure of the second embodiment will be described using the flowchart of FIG.
The user inputs a part or word of the document being browsed as an input keyword by the mouse operation (step S20), and selects a search service (step S21).

  A keyword is extracted from the browsed document (step S22). For keyword extraction, first, the range of keywords to be extracted is the range near the selected input keyword in the browsed document, the range displayed in the window, or the entire browsed document. Split into columns. Next, with reference to the basic keyword DB 113, the importance of each word in the divided word string is extracted, and the importance is arranged in descending order. A predetermined number (for example, about 3 words) of the sorted importance items are extracted and used as keywords.

  The evaluation points (or the number of appearances) corresponding to the keywords registered in the user keyword DB 14 are extracted, the evaluation points of the keywords are arranged in descending order, and a predetermined number (for example, about 3) of keywords with large evaluation points are extracted. An auxiliary keyword is set (step S23).

The user keyword DB 14 is updated using the keywords extracted from the browsed document (step S24).
If the extracted keyword does not exist in the user keyword DB 14, this keyword is newly registered. When newly registering, if an evaluation score is added to the keyword, this evaluation score is set as an initial value. If no evaluation score is added, “1” is set as the number of appearances.
When the extracted keyword exists in the user keyword DB 14, if an evaluation score is added to the keyword, the evaluation score is added to the same keyword, and the user keyword DB 14 is updated. When an evaluation point is not added to the keyword, the number of appearances is incremented by 1, and the user keyword DB 14 is updated.
Furthermore, the evaluation score may be added not only to the keyword update but also to similar words of the keyword. The evaluation points for similar words at this time may be accumulated, for example, by weighting the evaluation points of the keywords.

Next, a plurality of document files made up of a Web document or a document created by an application are searched by AND search of the input keyword and auxiliary keyword (step S25).
In this AND search, a search that emphasizes the input keyword is usually performed over the auxiliary keyword. However, in the case of an auxiliary keyword to which an evaluation score is added as attribute information, a search that reflects the evaluation score in weighting is performed.

  For each document in the search results, create a Web page to which attribute information such as URL indicating the title, abstract, the location where this document exists, and the location where the related document exists is added, and display it on the display device, output device, etc. / Output (step S26). This display order may be a ranking order as information that the user desires from search conditions such as input keywords and auxiliary keywords.

  With the above configuration, the content of the document being viewed is used in addition to the keyword input by the user while maintaining a comfortable operating environment with a conventional mouse, so that even one input keyword can be used by the user. The intended search result can be obtained.

<Embodiment 3>
The problem of using the user keyword DB 14 as in the above-described embodiment 2 is that it is not preferable to handle it as one user interest information when an individual has a plurality of independent interests such as work and hobbies. .
For example, when there are IT-related work interests, welfare and NGO activities as social interests, and music, art, and cooking as hobby interests, a single user keyword DB 14 can be used to achieve high search accuracy. I can't.
There are three ways to solve this:

  The first method is a method of classifying the interest information and inputting the classification of the current interest every time the user searches. However, the burden on the user is large and is the object of the present invention. The user does not match “Perform an accurate search by specifying one keyword”.

In the second method, first, the classification of the browsing document is automatically determined, and keywords having the same classification as this classification are extracted from the user keyword DB 14 with a large evaluation score. Next, the user keyword DB 14 is updated with the keywords extracted from the browsed document according to the classification of the browsed document.
This method can be realized by replacing the user keyword management unit 13 and the user keyword DB 14 of the second embodiment with the functions described above.

The third method is a method related to the third embodiment, and uses the co-occurrence appearance rate user keyword DB 15 instead of the user keyword DB 14.
FIG. 6 is a block diagram showing a functional configuration of the third embodiment in which auxiliary keywords are improved using the keywords extracted by the keyword extracting means 11. In the figure, the functional configuration of the third embodiment includes a user I / F unit 10, a keyword extraction unit 11, a user keyword management unit 13, a co-occurrence appearance rate user keyword DB 15, a search request unit 12, a search unit 20, and an information storage unit. 21 and result notification means 22. Here, the same functions as those in the first embodiment and the second embodiment are denoted by the same reference numerals, and only differences will be described below.

In the present invention, in order to represent the strength of the co-occurrence relationship, a keyword appearing in the browsed document is defined as “extracted keyword co-occurring with respect to the input keyword” with respect to the keyword input by the user. , The co-occurrence appearance evaluation point or the number of times of simultaneous appearance (hereinafter referred to as the co-occurrence appearance number) is used.
In the third embodiment, the keywords having the co-occurrence relationship and the co-occurrence appearance evaluation point or the number of times of co-occurrence appear are recorded in the co-occurrence appearance rate user keyword DB 15 illustrated in FIG.
In FIG. 7, the keyword in the column direction indicates an input keyword, the keyword in the row direction indicates a keyword extracted from the browsing document, and indicates that the keywords in the column direction and the row direction appear together. In the cell specified by the keyword in the column direction and the row direction, when the input keyword in the column direction is specified, the co-occurrence appearance evaluation score or the number of co-occurrence appearances of the keyword extracted from the document being viewed is displayed. Cumulatively set.

  The user keyword management means 13 refers to the co-occurrence appearance rate user keyword DB 15 and extracts the co-occurrence appearance evaluation point or the number of times of co-occurrence appearance of the keyword appearing together with the input keyword, and the extracted co-occurrence appearance evaluation point Alternatively, the number of co-occurrence appearances is arranged in descending order, and a predetermined number (for example, about 3) of keywords are extracted from the larger one and used as auxiliary keywords.

  Next, the user keyword management unit 13 refers to the co-occurrence appearance rate user keyword DB 15 and newly registers an unregistered keyword when an item for the input keyword and the extracted keyword is not registered. When newly registering, if an evaluation score is added to the extracted keyword, this evaluation score is set as the initial value of the co-occurrence appearance evaluation score. When the evaluation score is not added, “1” is set as the number of co-occurrence appearances.

  In addition, the user keyword management means 13 refers to the co-occurrence occurrence user keyword DB 15 and, when an input keyword and an extracted keyword exist, the evaluation is performed if an evaluation score is added to the extracted keyword. Points are added and the co-occurrence appearance rate user keyword DB 15 is updated. When an evaluation score is not added to the extracted keyword, the appearance count is incremented by 1, and the co-occurrence appearance rate user keyword DB 15 is updated.

  Here, the update of the co-occurrence appearance user keyword DB 15 after passing the auxiliary keyword to the search request means 12 eliminates the influence of the keyword extracted from the current browsing document on the evaluation score and the number of appearances. The auxiliary keyword is determined based on the history information so far.

  In addition, the co-occurrence rate user keyword DB 15 performs maintenance, for example, about once a month so that a keyword frequently used in the past is not selected as an auxiliary keyword when it is not frequently used recently. . In this case, each keyword of the co-occurrence appearance rate user keyword DB 15 holds the last update date and time of the evaluation score, and maintenance is performed so that the interval between the last update date and the current date and time increases and the evaluation score decreases. To do.

  Furthermore, not only the keyword extracted from the browsed document but also the evaluation score may be added to similar words of the keyword. The evaluation points for similar words at this time may be accumulated, for example, by weighting the evaluation points of the keywords.

Next, the processing procedure of the third embodiment will be described using the flowchart of FIG.
The user inputs a part or word of the document being browsed as an input keyword by a mouse operation (step S30), and selects a search service (step S31).

  A keyword is extracted from the browsed document (step S32). For keyword extraction, first, the range of keywords to be extracted is the range near the selected input keyword in the browsed document, the range displayed in the window, or the entire browsed document. Split into columns. Next, with reference to the basic keyword DB 113, the importance of each word in the divided word string is extracted, and the importance is arranged in descending order. A predetermined number (for example, about 3 words) of the sorted importance items are extracted and used as keywords.

  Referring to the co-occurrence appearance rate user keyword DB 15, the co-occurrence appearance evaluation point or the co-occurrence appearance number of the keyword appearing together with the input keyword is extracted, and the extracted co-occurrence appearance evaluation point or the co-occurrence appearance number is increased. They are arranged in order, and a predetermined number (for example, about 3) of keywords from the larger one are taken out and used as auxiliary keywords (step S33).

The co-occurrence rate user keyword DB 15 is updated using the input keyword and the extracted keyword (step S34).
With reference to the co-occurrence appearance user keyword DB 15, if the input keyword and the item for the extracted keyword are not registered, the unregistered keyword is newly registered. When newly registering, if an evaluation score is added to the extracted keyword, this evaluation score is set as the initial value of the co-occurrence appearance evaluation score. When the evaluation score is not added, “1” is set as the number of co-occurrence appearances.

  In addition, referring to the co-occurrence appearance rate user keyword DB 15, if an input keyword and an extracted keyword exist, if an evaluation score is added to the extracted keyword, the evaluation score is added and the common keyword is added. The occurrence rate user keyword DB 15 is updated. When an evaluation score is not added to the extracted keyword, the appearance count is incremented by 1, and the co-occurrence appearance rate user keyword DB 15 is updated.

  Furthermore, not only the keyword extracted from the browsed document but also the evaluation score may be added to similar words of the keyword. The evaluation points for similar words at this time may be accumulated, for example, by weighting the evaluation points of the keywords.

  Next, a plurality of document files made up of a Web document or a document created by an application are searched by AND search of the input keyword and auxiliary keyword (step S35). In this AND search, a search that emphasizes the input keyword is usually performed over the auxiliary keyword. However, in the case of an auxiliary keyword to which an evaluation score is added as attribute information, a search that reflects the evaluation score in weighting is performed.

  For each document in the search results, create a Web page to which attribute information such as URL indicating the title, abstract, the location where this document exists, and the location where the related document exists is added, and display it on the display device, output device, etc. / Output (step S36). This display order may be a ranking order as information that the user desires from search conditions such as input keywords and auxiliary keywords.

  With the above configuration, the content of the document being viewed is used in addition to the keyword input by the user while maintaining a comfortable operating environment with a conventional mouse, so that even one input keyword can be used by the user. The intended search result can be obtained.

<Embodiment 4>
In each of the above-described embodiments, the keyword extraction unit is an essential component. However, when the user keyword DB is used, even updating using only the input keyword is effective as context information.
The fourth embodiment considers a configuration in which the keyword extracting unit 11 is omitted from the second embodiment.

  FIG. 9 is a block diagram showing a functional configuration of the fourth embodiment. In the figure, the functional configuration of the fourth embodiment includes a user I / F unit 10, a user keyword management unit 13, a user keyword DB 14, a search request unit 12, a search unit 20, an information storage unit 21, and a result notification unit 22. It has become. Here, the same functions as those of the second embodiment are denoted by the same reference numerals, and only differences will be described below.

When the user inputs a keyword and a search instruction, the user I / F unit 10 passes a search request with the input keyword added to the user keyword management unit 13.
The user keyword DB 14 is a data file that holds the usage history of keywords input by the user, and maintains and manages the keywords and the total number of designated times for each input keyword.
The user keyword management unit 13 arranges the designated number of keywords extracted from the user keyword DB 14 in descending order, and extracts a predetermined number (for example, about 3) of keywords from the larger one as auxiliary keywords.

Next, the user keyword management means 13 refers to the user keyword DB 14 and newly registers the input keyword when there is no input keyword. When newly registering, “1” is set as the cumulative value of the designated number of times.
In addition, when the input keyword exists in the user keyword DB 14, the user keyword management unit 13 increments the number of times of use by one and updates the user keyword DB 14.

  Here, after the auxiliary keyword is passed to the search request means 12, the user keyword DB 14 is updated because the keyword extracted from the current browsing document has no influence on the evaluation score and the number of appearances. The auxiliary keyword is determined based on the history information.

  Further, even if the keyword is frequently used in the past, the user keyword DB 14 is maintained about once a month so that it is not selected as an auxiliary keyword when it is not frequently used recently. In this case, the last update date / time of the cumulative value of the number of times of use is stored in each keyword of the user keyword DB 14, and maintenance is performed so that the interval between the last update date and the current date / time increases and the evaluation score decreases. .

  Further, not only the update of the input keyword but also evaluation points may be added to similar words of the input keyword. The evaluation score for the similar word at this time may be accumulated by weighting the number of times the input keyword is used, for example.

Next, the processing procedure of the fourth embodiment will be described using the flowchart of FIG.
The user inputs a part or word of the document being browsed as an input keyword by a mouse operation (step S40), and selects a search service (step S41).

  The specified numbers of keywords extracted from the user keyword DB 14 are arranged in descending order, and a predetermined number (for example, about 3) of keywords is extracted from the larger one and used as auxiliary keywords (step S42).

The user keyword DB 14 is updated using the input keyword (step S43).
If the input keyword does not exist in the user keyword DB 14, this input keyword is newly registered. When newly registering, “1” is set as the initial value of the cumulative value of the number of times of use. When the input keyword exists in the user keyword DB 14, the use frequency is counted up by one and the user keyword DB 14 is updated.
Furthermore, not only the keyword update, but also evaluation points may be added to similar words of the input keyword. The evaluation points for similar words at this time may be accumulated by weighting the number of times the keyword is used, for example.

  Next, a plurality of document files made up of a Web document or a document created by an application are searched by AND search of the input keyword and auxiliary keyword (step S44). In this AND search, a search that emphasizes the input keyword is usually performed over the auxiliary keyword. However, in the case of an auxiliary keyword to which an evaluation score is added as attribute information, a search that reflects the evaluation score in weighting is performed.

  For each document in the search results, create a Web page to which attribute information such as URL indicating the title, abstract, the location where this document exists, and the location where the related document exists is added, and display it on the display device, output device, etc. / Output (step S45). This display order may be a ranking order as information that the user desires from search conditions such as input keywords and auxiliary keywords.

  With the above configuration, the content of the document being viewed is used in addition to the keyword input by the user while maintaining a comfortable operating environment with a conventional mouse, so that even one input keyword can be used by the user. The intended search result can be obtained.

(B) Advertising search system:
In the following description, as an example of an advertisement type search system, the user's interest is paid in return for providing a comfortable operation environment in which a document related to one keyword specified by the user is searched and the search result is provided to the user. This will be described using an advertisement search service that provides advertisement information closer to the thing and realizes a higher click rate. The advertisement search service will be described based on the information search system described above. However, the advertisement search service may be configured to perform only the advertisement type search service based on the keyword input by the user or the auxiliary keyword extracted from the viewed document. .
Moreover, the advertisement type search system of the present invention can be easily applied not only to the advertisement type search service for the information search service but also to the advertisement type search service for the dictionary service and the translation service.

<Embodiment 5>
FIG. 11 is a block diagram showing a functional configuration of an advertisement type search system according to Embodiment 5 of the present invention. In the figure, the advertisement type search system is a user interface (hereinafter referred to as user I / F) means 10. , Keyword extraction means 11, search request means 12, search means 20, information storage means 21, result notification means 22, advertisement search means 30, and advertisement information storage means 31. Here, the same functions as those in the first embodiment are denoted by the same reference numerals, and only differences will be described below.

The search request unit 12 passes the search request to which the auxiliary keyword extracted by the keyword extraction unit 11 and the input keyword input by the user are added to the search unit 20 and the advertisement search unit 30.
The advertisement search means 30 searches the advertisement information storage means 31 by AND search of the input keyword and auxiliary keyword passed from the search request means 12, and passes the searched advertisement content to the result notification means 22. Here, the advertisement information storage means 31 is at least one advertisement content database or file storing a plurality of advertisement information including advertisement contents provided in advance by an advertiser and keywords for searching for the advertisement.

  In this AND search, a search that emphasizes the input keyword is usually performed over the auxiliary keyword. However, in the case of an auxiliary keyword to which an evaluation score is added as attribute information, a search that reflects the evaluation score in weighting is performed. Further, in the advertisement search means 30, the input keyword and the auxiliary keyword may be weighted differently from the search means 20.

  The result notification means 22 converts the search result passed from the search means 20 and the advertisement content of the search result passed from the advertisement search means 30 by one of the following display methods, and passes the result to the user I / F means 10. .

(1) First display method:
When a plurality of pages can be switched and displayed as in the tab browser, the title, abstract, the location where this document exists, and related documents are searched for the search result passed from the search means 20 for each searched document. A Web page that is directly displayed as a list to which attribute information such as a URL indicating the location of the URL is added is created.
In addition, for the advertisement content of the search result passed from the advertisement search means 30, an instruction to display in the advertisement content dialog is issued to the user I / F means 10 (see FIG. 12).
(2) Second display method:
For the search result passed from the search means 20 so that it can be displayed by a normal browser, for each searched document, a URL indicating the title, abstract, the location where this document exists, and the location where the related document exists A web page that is created as a list to which attribute information such as the above is added and the advertisement content is displayed on this web page for the advertisement content of the search result passed from the advertisement search means 30 Create

Next, the processing procedure of the fifth embodiment will be described using the flowchart of FIG.
The user inputs a part or word of the document being browsed as an input keyword by the mouse operation (step S50), and selects a search service (step S51).

  A keyword is extracted from the browsed document, and this keyword is set as an auxiliary keyword (step S52). For keyword extraction, first, the range of keywords to be extracted is the range near the selected input keyword in the browsed document, the range displayed in the window, or the entire browsed document. Split into columns. Next, the importance of each word in the divided word string is arranged in descending order. A predetermined number (for example, about 3 words) of the sorted importance items are extracted and used as auxiliary keywords.

A plurality of document files made up of a Web document or a document created by an application are searched by AND search of the input keyword and auxiliary keyword (step S53).
In this AND search, a search that emphasizes the input keyword is usually performed over the auxiliary keyword. However, in the case of an auxiliary keyword to which an evaluation score is added as attribute information, a search that reflects the evaluation score in weighting is performed.

Further, the advertisement content provided by the advertiser is searched by AND search of the input keyword and the auxiliary keyword (step S54).
In this AND search, a search that emphasizes the input keyword is usually performed over the auxiliary keyword. However, in the case of an auxiliary keyword to which an evaluation score is added as attribute information, a search that reflects the evaluation score in weighting is performed. In this advertisement search, the input keyword and the auxiliary keyword may be weighted differently from the information search.

  For each document in the search results, create a Web page to which attribute information such as URL indicating the title, abstract, the location where this document exists, and the location where the related document exists is added, and display it on the display device, output device, etc. In addition, the searched advertisement content is displayed on the advertisement content dialog screen (step S55). This display order may be a ranking order as information that the user desires from search conditions such as input keywords and auxiliary keywords.

  With the above configuration, it is possible to provide an advertisement that more closely matches the user's interest when the user inputs one keyword while maintaining a comfortable operating environment with a conventional mouse. Can be improved.

<Embodiment 6>
Incidentally, there is a case where fairness of search results is questioned as one problem of the advertisement type search service. The high click rate of the advertisement-type search service is that only the advertisement content corresponding to the input keyword, that is, the user interest information can be displayed. However, in the conventional advertisement-type search system, the information search result specified by the user and the information about the advertisement Is displayed in a stunning manner, and there is a problem that it is difficult for the user to distinguish between the information he wants and the advertisement.

  In order to avoid this, the advertisement type search system of the sixth embodiment solves this fairness problem by separately presenting the information search result designated by the user and the advertisement content by any of the following methods. .

(1) First method:
An advertisement search is a method of searching only with auxiliary keywords. Although this method is logically fair in the sense that the input keyword is not used, if the input keyword is an important keyword in the user browsing document, the auxiliary keyword may include the input keyword. Compared with the second method, the fairness is low.

(2) Second method:
An advertisement search is a method in which the input keyword is excluded from the auxiliary keyword and the search is performed using only this auxiliary keyword. This method can provide sufficient fairness of search results because it can delete advertising content related to information that the user is not directly interested in.

The functional configuration of the sixth embodiment is the same as that of the fifth embodiment, except that the advertisement search unit 30 performs a search by correcting the auxiliary keyword by one of the above two.
That is, the advertisement search means 30 receives the input keyword and the auxiliary keyword from the search request means 12, corrects the auxiliary keyword by one of the above-described two methods, and refers to the advertisement information storage means 31. Then, the advertisement content is extracted by AND search of only the corrected auxiliary keyword.

  With the above configuration, since the advertisement content related to the input keyword can be excluded from the search result, it is possible to provide an advertisement that maintains fairness even when the input keyword is not user interest information.

<Modification of Embodiments 5 and 6>
In the auxiliary keyword acquisition method of the fifth and sixth embodiments, the keyword is extracted from the document being browsed as in the first embodiment, and is used as the auxiliary keyword. In the present modification, the auxiliary keyword acquisition unit may be replaced with the auxiliary keyword acquisition method in the second to fourth embodiments.
In the modified example replaced in this way, it is possible to provide advertising content that better matches the user interest of the user.

By configuring each function in the first to sixth embodiments like the user site and the service site in the seventh embodiment, the following effects can be provided.
In a conventional search system, a high click rate is realized by presenting an advertisement related to a keyword inputted by the user. To achieve this high click rate, user interest information is acquired in addition to the input keyword. It is effective. However, the user interest information is information related to user privacy, and it is difficult to obtain the user's consent unless there is a merit for the user.
Furthermore, in the search engine method that obtains the URL of the document that the user is browsing, information on which document the user browsed is acquired, and all the information of the document can be acquired by the URL, so damage to the privacy Is likely to give.

  However, as in the seventh embodiment, what is passed from the user site 100 to the service site 200 is limited to the acquisition of context information such as the input keyword and the keyword extracted from the document viewed by the user. It is difficult to specify the document that the user was browsing from such keywords, and the possibility of causing damage to privacy is reduced.

<Embodiment 8>
However, the configuration as in the seventh embodiment has the following problems.
(1) Even if only the auxiliary keyword is transferred to the service site, if it is accumulated at the service site, there may be a problem in the privacy of the user.
(2) When the user keyword DB and the co-occurrence appearance rate user keyword DB are maintained and managed by the user keyword management means on the service site, the service provider can access these databases at any time. Analysis and statistical processing for many users are possible. Therefore, the service provider can further improve the search accuracy and advertisement content click rate based on this analysis result, but the analysis result on the user interest information may be related to the privacy of the user. If information is leaked, there is a possibility of causing damage to the user.

In order to deal with the above problems, in each of the above-described embodiments, when a keyword or auxiliary keyword extracted from a browsing document other than the input keyword is passed to the service site, the privacy or Security information was excluded.
There are the following three patterns for applying this filter.

(1) First pattern:
The keyword extraction unit 11 extracts an auxiliary keyword from the browsed document, the transfer filter unit 17 filters the auxiliary keyword, and the search request unit 12 passes the filtered auxiliary keyword to the service site search unit or advertisement search unit. Yes (see FIG. 20).
(2) Second pattern:
The keyword extraction unit 11 extracts keywords from the browsed document, the transfer filter unit 17 filters the keywords, and the search request unit 12 passes the filtered keywords to the user keyword management unit of the service site (see FIG. 21). ).

(3) Third pattern:
This is a pattern in which the auxiliary keyword obtained by the user keyword management means 13 is filtered by the transfer filter means 17 and the filtered auxiliary keyword is passed to the service site search means and advertisement search means by the search request means 12 ( (See FIG. 22).
The database managed by the user keyword management means can be applied to both the user keyword DB and the co-occurrence rate user keyword DB.

  Next, the function of the transfer filter means 17 will be described in detail.

(1) Checking method with user:
In the case of the first pattern, the auxiliary keyword extracted from the browsed document by the keyword extracting unit 11 is targeted, and a list of the auxiliary keyword is presented to the user in the dialog illustrated in FIG. 23, for example.
The user selects an auxiliary keyword to be prohibited from transfer from the displayed list of auxiliary keywords, and clicks the delete button. When there are no more auxiliary keywords that you want to prohibit transferring, click the transfer button.
The transfer filter means 17 passes the auxiliary keyword (auxiliary keyword permitted to be transferred) left when the transfer button is clicked to the service site search means and advertisement search means via the search request means 12.

According to this method, a keyword to be transmitted to the service site can be confirmed in advance, and a specific keyword can be deleted if there is a problem.
However, this method requires the user to determine whether or not transfer is possible every time, but is effective when the probability of transfer prohibition is small or when the number of auxiliary keywords passed to the transfer filter means 17 is small.

Similarly, in the case of the second pattern, the keyword extracted from the browsing document by the keyword extracting unit 11 is targeted, the transfer prohibited keyword is deleted, and the remaining keyword is transferred to the service site via the keyword transferring unit 16. Pass to user keyword management means.
Further, in the case of the third pattern, the auxiliary keyword selected by the user keyword management means 13 is targeted, the transfer prohibition keyword is deleted, and the remaining auxiliary keyword is retrieved via the search request means 12 as a service site search means or Pass to advertisement search means.

  When this method is combined with the methods (2) and (3) described below, a keyword that is automatically determined to be untransferable or transferable can be determined to be transferable or untransferable at the discretion of the user.

(2) Method of referring to transferability table for keywords:
First, a secret keyword such as a development code name is stored in advance in the word table as a transfer-prohibited keyword.
In the case of this registration, a list of keyword table keyword states is displayed in response to a user request (see FIG. 24). The types of keywords include “common” that is commonly set in the organization by the security policy and cannot be edited by general users, and “user setting” that can be set by general users.
In accordance with the authority, the user adds, deletes, and edits the transfer prohibition keyword and updates the word table.
In the above word table, keywords for which transfer is prohibited are stored. However, only keywords for which transfer is permitted may be stored, or the keywords that have been registered can be transferred or not. You may make it memorize.

In the case of the first pattern, the auxiliary keyword extracted from the browsed document by the keyword extraction unit 11 is targeted, and whether or not transfer is possible is determined by comparing with the keyword stored in the word table, and only the auxiliary keyword that can be transferred. Is passed to the search means and the advertisement search means of the service site via the search request means 12.
In this method, it is possible to automatically apply a filter so that a specific word (project name or the like) is not included in the keyword of the document viewed by the user.

Similarly, in the case of the second pattern, the keyword extracted from the browsed document by the keyword extracting unit 11 is targeted, and whether or not transfer is possible is determined by comparing with the keyword stored in the word table. Are transferred to the user keyword management means of the service site via the keyword transfer means 16. In this case, only transferable keywords are registered in the user keyword DB or the co-occurrence rate user keyword DB.
In the case of the third pattern, the auxiliary keyword selected by the user keyword management means 13 is targeted, the transferability is judged by comparing with the keyword stored in the word table, and the transferable auxiliary keyword is requested to be searched. The data is passed to the service site search means and advertisement search means via the means 12.

(3) A method of referring to the availability table for the document ID:
A browsing document may be required to prohibit transmission of all information related to the document. For example, there are private letters, confidential documents related to corporate security, etc. In such cases, it is more convenient to handle whether transfer is possible in units of documents.
For this purpose, first, a document ID table including a transfer prohibition document ID table and a transfer prohibition attribute table is stored in advance.

For this registration, the dialog illustrated in FIG. 25 is displayed, and the name of a document to be transferred to the service site and its attributes (attributes include “normal”, “confidential”, “confidential”, etc.) are input. Click the registration button to register it in the list of prohibited transfer documents. Even if the attribute is “normal”, all the documents registered here are automatically handled as transfer prohibited documents.
Further, when changing a document displayed in the transfer prohibited document list to a transferable document, the document can be selected in the transfer prohibited document list and deleted with the “registration delete button”.
The documents registered in the document ID table are registered as illustrated in FIG.

  Further, in this document ID table, only transferable document IDs are registered, and if the target document is not registered in the document ID table, it may be determined that transfer is prohibited, or Further, whether transfer is possible or not may be registered for the document ID.

In the case of the first pattern or the second pattern, the attribute information of the browsed document is compared in the transfer prohibition attribute table, and if it is registered as the transfer prohibition attribute, the extracted keyword is not transferred. However, if the browsing document attribute information is not registered as a transfer prohibition attribute or is registered as a transfer prohibition attribute, the browsing document ID is compared with the transfer prohibition document ID table and registered as a transfer prohibition document. If so, the extracted keyword is not transferred.
According to this method, it is possible to automatically determine whether or not the keyword extracted from the document to be browsed can be transferred with reference to the document ID table.

  Furthermore, if the transfer filter means is applied to the browsed document when the search instruction is issued, it is not necessary to extract a keyword for the transfer-prohibited document.

  Moreover, you may make it confirm a user the result of having evaluated the browsing document in the document ID table. For example, the message is displayed on the dialog shown in FIG. 27, and the user refers to the displayed comment, and if it is inappropriate, clicks a change button for transfer permission or transfer prohibition, and clicks a confirmation button. When there is a change to transfer permission or transfer prohibition, registration is updated in the document ID table.

(4) When combining the filters (2) and (3):
As a first example, it is possible to determine a keyword forbidden to transfer by applying the word table of (2) to a keyword extracted from a document that can be transferred by the method of (3).
As a second example, conversely, the keywords that can be transferred can be determined by applying the word table of (2) to the keywords extracted from the transfer-prohibited document by the method of (3). .
In this case, since it is possible to determine whether or not transfer is possible for each keyword with respect to the keyword that is determined whether or not transfer is possible, privacy safety is further enhanced.

(5) When combining the filters (2) and (1):
By applying the word table (2) to the extracted keywords, the keywords are divided into transferable keywords and transfer-prohibited keywords. For example, each list is displayed in a dialog as shown in FIG. The user changes the displayed keyword indicating whether transfer is permitted or prohibited, if inappropriate. To change, select the keyword you want to change and click on the move button to enable transfer or disable transfer. Click the Confirm button when there are no changes. When the confirmation button is clicked, the keywords set for transfer enable and transfer prohibition are registered and updated in the word table.
In this case, it is possible to finally confirm whether or not transfer is possible for a keyword that has been automatically determined to be transferable, and privacy safety is further enhanced.

(6) When combining the filters of (3) and (1):
The document ID table of (3) is applied to the extracted keywords, and the evaluation is divided into keywords that can be transferred and keywords that cannot be transferred. For example, each list is displayed in a dialog as shown in FIG. The user changes the displayed keyword indicating whether transfer is permitted or prohibited, if inappropriate. To change, select the keyword you want to change and click on the move button to enable transfer or disable transfer. Click the Confirm button when there are no changes.
In this case, it is possible to finally confirm whether or not transfer is possible for a keyword that has been automatically determined to be transferable, and privacy safety is further enhanced.

(7) When the filters (3), (2), and (1) are combined:
The keywords extracted from the browsing document and the transferability thereof are determined by the method (3), the word table of (2) is applied to these keywords to correct the transferability of the keywords, Each keyword list is displayed in a dialog as shown in FIG. The user changes the displayed keyword indicating whether transfer is permitted or prohibited, if inappropriate. To change, select the keyword you want to change and click on the move button to enable transfer or disable transfer. Click the Confirm button when there are no changes.
In this case, it is possible to finally confirm whether or not transfer is possible for a keyword that has been automatically determined to be transferable, and privacy safety is further enhanced.

  By configuring the transfer filter means as described above, in the conventional method of acquiring a URL, it was only possible to select whether or not to acquire, but in the present invention, various levels of filtering can be performed.
